1.4. Precautions for Use
This document contains information that all operators should be aware of and understand before using the
Inocenter. This information highlights situations that could result in serious damage and indicates the precautions
that should be taken to avoid them.
Before any use of the Inobox control module, check that all operators:
• have previously be trained by the company Sames, or by their distributors registered by them for this
purpose.
• have read and understood the user manual and all rules for installation and operation, as laid out
below.
It is the responsibility of the operators’ workshop manager to ensure these two points and it
is also his responsibility to make sure that all operators have read and understood the user
manuals for any peripheral electrical equipment present in the powdering area.
1.5. Warnings
It is imperative that anyone wearing a pacemaker does not use the equipment and does not
enter the projection area.
High voltage can cause the pacemaker to malfunction.
This equipment may be hazardous if it is not used, disassembled and reassembled in
accordance with the rules indicated in this manual and in any applicable European Standard or
national safety regulations.
Equipment performance is only guaranteed if original spare parts distributed by Sames
are used.
During the cleaning cycle of the powder station, it is imperative to block the powder plunger
on its support.
This equipment should only be used outside of an explosive atmosphere. The equipment
should only be used in a well-ventilated area to reduce health, fire and explosion hazards. The
effectiveness of the exhaust ventilation system should be checked daily.

1 The operator must wear shoes according to standard EN ISO 20344 and the insulation resistance measured
must not exceed 100 MΩ.
2 The protective clothes, including gloves, must conform to standard EN 1149-5 and the insulation resistance
measured must not exceed 100 MΩ.
3 Make sure that the pneumatic pressure inside is completely exhausted before adjusting or servicing
pressurized systems or parts.
4 Using individual protection equipment will limit the risks of contact and/or inhalation of toxic product, gas,
vapours, fog or dusts that can be produced while using the equipment. The user has to follow the coating
product manufacturer’s recommendations.
5 Appropriate measures must be taken to prevent potential energy being present in the equipment during
periods of non-use and/or when the equipment is out of service.
6TheInocenter powder station must be maintained regularly in accordance with the indications and instructions
given by Sames. Repairs must be carried out in strict accordance with these instructions.
7 Unplug, lock out and turn off electrical equipment before servicing electrical equipment.
8 Turn off all electrical or electrostatic equipment immediately, even if the operator is exposed to a slight electric
shock. Do not restart the equipment until the problem has been diagnosed and resolved.
9 The powder station, especially the vibrating table and all conductive structures placed in or near the work place
must be electrically connected to the protective grounding system of the power supply.
10All grinding or welding work on metal products carried out at a distance of less than 5 meters from the powder
station is prohibited if the following safety measures are not observed
• The powder station must be protected by a cover made of non-flammable (or hardly flammable) material.
• A person equipped with a fire extinguisher must monitor the environment of the powder station during the
work.
11The powder station must not support a mass other than that of the equipment originally intended to be
mounted on or around it. The structure of the powder station is self-supporting. In no case is the powder station
designed to support the mass of an operator working on its roof, the mass of a part of the building or any other
load.
12The floor on which the power plant is installed must have a strength of more than 400 kN/m2.

1.6. Important recommendations
1.6.1. Ventilation
Do not start the powder application with the Inocenter until the ventilation system of the spray booth is switched
on. If the ventilation is turned off, toxic substances or dust may remain in the spray booth and cause a risk of fire,
poisoning or irritation.
1.6.2. Ambient temperature
The Inocenter powder station is designed to normally operate at an ambient temperature comprised between 0°C
and + 40°C.
The storage temperature must never exceed +60°C.
This powder distribution plant Inocenter is usually connected to a filter unit via a ventilation
duct.
A filter explosion protection system in accordance with the ATEX Directive 2014/34/EU is
required.
Sames recommends to install a spark detector in the enclosure of the power station
connected to a CO2 injection system in the ventilation duct.

2 Automatic cleaning of:
•powderpumps,
• powder supply hoses,
• the inside of projectors and guns,
• powder recycling hose.
• powder tank.
The powder station can operate autonomously.
It is then controlled from the keyboard located on the front of the electro-pneumatic cabinet (see DRT6457 for the
Inomaster Platinum cabinet). The PLC monitor allows the operator to be guided and to follow his actions in real time.
It indicates to the operator the status of the powder unit (defects, cleaning steps, operations to be carried out).
2.2. Equipment overview
2.2.1. Vibrating table
The table, a 20kg powder box support, is equipped with an electric vibrator to facilitate the flow of the powder during
the pumping phase.
During the cleaning phase, the table, which is mobile, must be moved manually under the tank drain valve in order to
empty it.
Once cleaning is completed, return the table to its initial position.
When you have finished cleaning, return the table to its original position.
2.2.2. Powder transfer pump
This pump, equipped with 4 sleeves, allows the transport of new powder from the box to the fluidized tank.
During the production phase, the operation of the pump is managed by the level sensors of the tank.
The transport capacity of this pump, with a new powder box, is around 300 kg/min.
When starting the installation, it is necessary to force the filling of the tank until the information: "central OK" is
obtained.
2.2.3. Tank
This fluidized tank allows the distribution of powder to the projectors through a set composed of a sleeve valve and
a venturi type pump.
This tank can be equipped with a maximum of 24 pumps. It is equipped with 2 powder level detectors to ensure the
management of the filling and to maintain a constant level during the production phase.
An electric vibrator guarantees a good fluidization for difficult powders.
The tank is connected directly to the ventilation duct via a valve mounted on a pneumatic cylinder. This flap allows
to significantly increase the suction flow when it is open during the cleaning phases.
The tank must be emptied every evening at the end of the shift.

2.5. Operating principles
2.5.1. Powder equipment
The Inocenter powder unit is part of the Sames powder range.
2.5.2. New powder supply
The supply of new powder starts when the tank is filled for the first time, and in the production phase when the high
level sensor is lost, followed by an adjustable delay. The pump transfers the powder from the container to the tank.
Sleeve valve QR11 open and sleeve valve QR23 closed.

2.5.3. Blowing out the new powder supply
During a color change or when emptying the tank, the supply lines for new powder are blown by air streams to ensure
effective cleaning.
The air streams are sent successively to the suction pipe and to the tank.
2.5.4. Recycled powder supply to tank (production phase)
The recycled powder comes from the bottom of the cyclone or is then transported by the flip flop system of the
sleeve valves to the tank. Recycling of the powder starts when the high level sensor in the tank + tempo is lost. Airs
T21A and T22A are transport airs to evacuate the powder to the tank.

2.5.5. Recycled powder supply to th box powder (powder recovery phase before a change of colour
or end of production)
During a colour change or at the end of production with recovery of work in progress. The recycled powder coming
from the bottom of the cyclone is transported by the flip flop system of the sleeve valves to the powder box. Airs
T21A and T22A are transport airs to evacuate the powder to the tank. The sleeve valves QR10 and QR24 are closed.
2.5.6. Blowing of the recycled powder supply circuit
The powder ducts are cleaned alternately from the air tank to the tank (EVM21 and QR 48 closed), from the air tank
to the ventilation (QR10&EVM21 closed), from the air tank to the cyclone (QR10&QR48 closed).

2.5.7. Draining the powder tank
The tank is emptied when the colour is changed or when production is completed.
2.5.8. Powder supply for sprayers (powder hose)
The powder supply to the projectors is managed by the venturi pump. The injection air acts on the powder flow
and the dilution air on the transport air to bring the air/powder mixture to the projector in a homogeneous manner.

2.5.9. Blowing out powder feed pipes for sprayers.
The powder hoses of the sprayers are blown by two air supply sources.
1 By controlling the injection and dilution valves at maximum setting (once the powder tank has been emptied).
2 By alternately ordering KK20 valves L01... LXX. Air streams are sent to the sprayers and to the tank when the
QRPLXX sleeve valves for the air streams are opened.
2.5.10. Tank blowing
The tank has its own air supply via two air inlets on the rear panel. Valves QR45 and QR44 are closed during cleaning
air trains. The tank is also cleaned by the new and recycled powder supply pipes during the cleaning phases.

2.5.11. Blowing out the dense phase powder pump
The powder pump is blown by several air supply sources:
1 Via the KK9 valve, which sends trains of air at network pressure through the porous filters
1 filters of the pump to clean them and evacuate the powder into the ventilation system through the draw pipe.
2 Valves QR 23 and KK 23 send air streams to the pump's chambers A&B (depending on the opening of valves
PV1...PV4).
